Feasibility study = Assessment of the mining deposit Cost estimation methods = Part of the feasibility study Investment analysis = Determining economic returns and justifying investments Risk = Consideration in investment analysis
Match the following concepts related to interest rates with their explanations:
Productive use of money = Benefit in the future Time value of money = Explain the relationship between present and future value Interest = Related to present and future value Cost of capital funds = Consideration in investment analysis
Match the financial concept with its description:
Time value of money = A dollar today is worth more than a dollar in the future due to the potential for investment and productive use Interest (I) and interest rate (i) = The difference between the amount of money lent and repaid, and the rate used to relate present and future value Accounting Rate of Return (ARR) = Measures the average return during a period against the average investment, and does not account for the time value of money Net Present Value (NPV) = Difference between the present value of cash flows and cash outflows over a period of time, calculated using a discount rate
Match the financial concept with its example calculation:
Initial investment with 10% interest rate = $5,000 investment becomes $5,500 after one year ARR calculation for new machine = Machine costing $420,000, with increased revenue of $200,000 and annual expenses of $50,000 Payback Period calculation = $5,000 investment with $100 monthly savings results in a 4.2-year payback NPV calculation for project = Initial capital investment of $20,000, generating revenues of $4,000, $10,000, and $15,000 over three years with a 7% interest rate
Match the process with its description in mining and metallurgy:
Hydrometallurgy = Involves leaching, solution purification, and metal recovery Pyrometallurgy = Involves roasting, smelting, and converting Mineral processing = Differences between mineral processing and metallurgy, and the processes of hydrometallurgy and pyrometallurgy Metallurgy = Differences between mineral processing and metallurgy, and the processes of hydrometallurgy and pyrometallurgy
Study Notes
Financial Concepts in Mining and Optimization
- The time value of money is based on the idea that a dollar today is worth more than a dollar in the future due to the potential for investment and productive use.
- Interest (I) is the difference between the amount of money lent and the amount repaid, and can be related to the present and future value using the interest rate (i).
- An example calculation illustrates how an initial investment of $5,000 with a 10% interest rate becomes $5,500 after one year.
- The Accounting Rate of Return (ARR) measures the average return during a period against the average investment, and does not account for the time value of money.
- A practical example of ARR calculation for a new machine costing $420,000, with increased revenue of $200,000 and annual expenses of $50,000, is provided.
- The Payback Period formula calculates the time it takes to recover the cost of an investment and is used as a decision criterion for project acceptance.
- An example demonstrates the payback period for a $5,000 investment with $100 monthly savings, resulting in a 4.2-year payback.
- Net Present Value (NPV) is the difference between the present value of cash flows and cash outflows over a period of time, and is calculated using a discount rate.
- An example calculates the NPV for a project requiring an initial capital investment of $20,000, generating revenues of $4,000, $10,000, and $15,000 over three years with a 7% interest rate.
- The lecture covers the differences between mineral processing and metallurgy, and the processes of hydrometallurgy (leaching, solution purification, and metal recovery) and pyrometallurgy (roasting, smelting, and converting).
- Students are reminded to check their LU email and D2L regularly, and about the upcoming field trip to Glencore Smelter on Nov 23rd and the final exam on Dec 7th.
- The lecture also emphasizes additional resources available on D2L and the coverage of B-GYM from Lec10 to the end.
